This document is about the functional specification of MF1 IC S50 card IC. It introduces the features of the card, including function description, data integrity, security, memory organization and access conditions.
The MF1 IC S50 is a contactless smart‑card IC designed for payment and ticketing applications. It operates at 13.56 MHz with a high‑speed 106 kBaud RF interface, allowing transactions within 100 mm of a reader in less than 0.1 s. The device includes built‑in security such as three‑pass authentication, data encryption, and unique serial numbers.
Memory is organized into 16 sectors, each containing four 16‑byte blocks, for a total of 8 Kbit EEPROM. The IC provides flexible access conditions, multi‑application support, and a data retention of 10 years with a write endurance of 100 000 cycles. Typical transaction times are 3 ms for identification, 2.5 ms to read a block, and 8.5 ms to write a block.
